Unfortunately, the game you get for your $5 isn't at all like a full game. You are given three short missions that, if you can manage to beat them on the first try, will last you about fifteen minutes. The game instead gives you the option to pay another five dollars for one of their three extra mission packs, which contain six missions each. The Wii doesn't offer demos like the other two major consoles, but this feels like paying 5 dollars to play a demo. Be ready to pay all 20 dollars if you like it, or else you'll feel cheated when you see credits roll after only playing for half an hour.
